Air Entered in the Cycle

1. Symptoms seen in refrigerating cycle

• Both 

LO

 and 

HI

 pressure side (1), (2) pressures too high.

LO

 pressure side (1)

0.20 to 0.35 MPa (2.0 to 3.5 kgf/cm

2

, 28.4 to 49.8 psi)

HI

 pressure side (2)

1.96 to 2.45 MPa (20 to 25 kgf/cm

2

, 284.5 to 355.6 psi)

LO

 pressure side (1) piping not cold when touched.

2. Probable cause

• Air entered in refrigerating cycle.

3. Solution

• Replace receiver.

• Check compressor oil contamination and quantity.

• Evacuate and recharge new refrigerant. (See page 10-S19.)

NOTE

• The above cycle can be seen when the cycle is charged

without evacuation.

Moisture Entered in the Cycle

1. Symptoms seen in refrigerating cycle

• The air conditioner operates normally at the beginning, but

over time, 

LO

 pressure side (1) pressure is 

vacuum

 and 

HI

pressure side (2) is low pressure.

LO

 pressure side (1)

Vacuum

HI

 pressure side (2)

0.69 to 0.98 MPa (7 to 10 kgf/cm

2

, 99.6 to 142.2 psi)

2. Probable cause

• The  moisture  in  the  refrigerating  cycle  freezes  in  the

expansion  valve  orifice  and  causes  temporary  blocking.

After a time, the ice melts and condition returns to normal.

3. Solution

• Replace receiver.

• Remove  moisture  in  cycle  by  means  of  repeated

evacuation.

• Recharge  new  refrigerant  to  the  proper  level.  (See  page

10-S19.)
